Answer: It doesn't matter, the violas are still late.

The first man said, "I'll have a glass of H2O". The second man said, "I'll have a glass of H2O2'. (Too)

I remember from HS chemistry class: "Little Johnny took a drink, of which he'll take no more. For what he thought was H2O was H2SO4."

Do you guys know of an on line pharmacy where I can buy all that cool stuff??

My local pub doesn't even carry some local craft beers, so I am surprised that barmeister had some H202 on hand; the pure solution is highly unstable. (CAUTION: non-funny info follows!)
It is commonly available in 3% and 6% water solution. A warning label should say:
Large oral doses of hydrogen peroxide at a 3% concentration may cause irritation and blistering to the mouth, throat, and abdomen as well as abdominal pain, vomiting, and diarrhea.
